Kristi Noem says she plans to use "every single one"

Washington — Department of Homeland Security Secretary Kristi Noem said Sunday that she plans to use the "broad and extensive" authorities of her role to follow through on President Trump's promises.

"I plan to use every single one of them to make sure that we're following the law, that we are following the procedures in place to keep people safe, and that we're making sure we're following through on what President Trump has promised — that he's going to make America safe again," Noem said on "Face the Nation with Margaret Brennan."

The comments came as DHS has been administering polygraph tests to its personnel to determine who may be leaking information to the media about its ongoing immigration raids, an agency spokesperson confirmed to CBS News Saturday.

Noem said on Sunday that the tests will continue, while pledging that the leakers will be prosecuted — and could face up to 10 years in federal prison.

"Anyone who is leaking information outside of how something is planned for the safety of those law enforcement officers needs to be held accountable for that," Noem said.
